ABSTRACT:
Power is transmitted from a motor to a pump or other device through a variable speed drive having a vertical input shaft disposed above a coaxial vertical output shaft. The shafts are rotatably supported by corresponding bearings retained within hub portions of a housing, and interfitting annular clutch plates and clutch discs are alternately connected to the input and output shafts. The clutch discs and plates are forced together by a fluid actuated piston, and the input shaft defines a passage for directing lubricating and cooling oil into the center of the clutch plates and discs so that the oil flows outwardly into an annular collecting chamber surrounding the clutch plates. The housing defines an annular oil reservoir chamber surrounding the oil collecting chamber, and heated oil is pumped from the collecting chamber through a heat exchanger and into the reservoir chamber. The top wall of the housing defines a horizontally extending passage through which oil is forced from the top of the reservoir chamber to the oil inlet passage within the input shaft.
